Thanks – it might be a good idea to bring it along, but I think the club already has like a 2′ x 3′ whiteboard for the big launches.W

I wonder if using shielded or twisted pair wiring would resolve some or all of the RF coupling issue? One problem I note with most altimeters is that except for the power supply negative terminal, there’s not much in the…   Read more»

I would expect separation to be an absolute requirement after Mike’s experience with his other transmitter rig although that was operating at significantly higher power than I expect the collars to transmit with.Warren

Thank you Mike. Very much appreciated. I’ve got to coordinate with Jeremiah as the development website is now running on a virtual machine on his laptop and he’s got a large code dump we’re almost ready to roll out. We…   Read more»

Thanks Mike for putting this together. I just ordered 2 of the dog collars and will coordinate with you and Elvis on the collar # when I fly.This has the potential to be the best thing to happen to rocket…   Read more»

Most definitely. Somewhere around here I have an article printout from an old QSL magazine on the design and construction of small 3 to 18 element Yagi’s for 70cm bands. If I find it, I’ll post it here on the…   Read more»

Don’t take me wrong – I’m far from talking about the “big boys” telling the “little boys” what cool toys they can play with – sorry if it sounded that way. I am far from a “big boy” myself -…   Read more»

Actually, the Adept system is great and quite cheap ($60) compared to any other transmitter. Until this winter, we had fewer than 10 people in the club who ever flew transmitters with most of them borrowing the 3 or 4…   Read more»

The problem with that is the ID morse code sequence only happens once per minute and the tracking beeps are every 2 seconds I beleive. 90% of tracking is homing in on the regular beeps and not on the ID…   Read more»

One key issue is that many folks have their transmitters mounted in such a way that it has to be turned on well before launch – while they’re in final prep of the bird. Personally, I know with one of…   Read more»

Keep in mind that MOST NCR folks using tracking are using the Adept transmitter on 433.75Mhz. You absolutely must coordinate with the LCO and all other flyers using tracking. In general, tracking is not used at NCR launches for flights…   Read more»

hold off for me until you have a standard production unit.Warren

My only suggestion would be to change the data output frequency on the USB port from 1Hz to 10Hz or ideally 100Hz… or better yet, make it polled.Warren

I buy glass fabric from a variety of sources. http://www.fiberglast.com, http://www.sollarcomposites.com, http://www.advancedcomposites.com... and Colorado Plastics (??) in Fort Collins. I also buy most of my carbon fiber on Ebay.Warren

Good luck to you Brian. All our best. When you get tired of the rain, we’ll still be here flying.Warren

Thanks Art. I’m flying off the Extreme pad or the pad Mark Lionberger donated to the club. I need a 1515 rail for my project.By the way, it’s a 5″ project, just under 9′. I’ll be flying it on either…   Read more»

I’ve already started using it Ken. Booster stage for a 2 stage MD bird. Probably a J570 booster and maybe an I600 second stage.Warren

My wife is probably very glad but doesn’t know it yet that I gave up using paper and phenolic for rockets or else our garage would look like that.One interesting thing, my wife came back from the fabric store a…   Read more»

If you sell 1/2″-13 stainless threaded rod, I want some. Short of ordering from McMaster-Carr, I can’t find it anywhere locally. How much for a 12″ chunk?Warren

Now we’re wandering pretty far afield from where this started which was John looking for a 3/8″ eye nut and then apparently on the flavors and colors of Locktite.I was particularly found of the look on Joe Latrell when I…   Read more»
